Maximum Size Of An Array?

Jan 13, 2010

What is the maximum size of a multidimensional array in VB.NET (in my case two-dimensional)? I'm using Visual Studio 2008, Framework 3.5 I found in msdn [URL]: "The length of every dimension of an array is limited to the maximum value of a Long data type, which is (2 ^ 64) - 1. The total size limit of an array varies, based on your operating system and how much memory is available. Using an array that exceeds the amount of RAM available on your system is slower because the data must be read from and written to disk." However, I am trying to use an array of data type single, with dimensions 64513 by 301 but Visual Studio seems to freeze when I execute the line to redimension the array ( Redim myArray(64513, 301) ). I have 4Gb of RAM and am using Windows XP (32-bit).

Change Size Of A Byte Array?

Jun 12, 2009

My app is receiving data in blocks but I don't know what size data will be received until it is finished, unlike file reading. So my app loads the data in chunks of 1024 bytes and then stops when there is no data to read. My question is, is it possible to keep increasing the size of a byte array as the data is being received?

Get The Size Of The Array And Not The Number Of Items In It?

Nov 3, 2009

When you use array.length you get the size of the array and not the number of items in it.

For example:

Dim MyArray(10) as String
MyArray(0) = "Potato's"
MyArray(1) = "with"
MyArray(2) = "salt!"
MyArray.Length will return 11

How do I get the number 3? I am creating a class library so it's kinda hard to keep testing all kinds of methods until I get the right one .

How To Determine Size Of Dynamic Array

Jul 28, 2011

I'm trying to find the sum of all the digits that make up the number 2^1000, which you may have guessed is from Project Eula. I think it's good so far except I'm just learning about arrays and dynamic arrays, so how will I know what the size of the index will be so I can specify when the Do loop should stop so I don't get an indexoutofrange exception?

vb.net
Dim BigNumber As Double = 2 ^ 1000
Dim DigitArray() As Char = BigNumber.ToString.ToCharArray
Dim Index As Integer = 0
Dim SumOfDigits As Integer = 0

Limiting Array Size Through Class?

May 29, 2009

Is it possible to have a UD Class that can limit how big it can grow as an array?

for example:dim var(10) as class this would throw an exception cause the class will only grow up to 5 elements.dim var(4) as class valid cause it is under the 5 element rule dim var(4, 10) as class invalid cause the 2nd dimension is above the 5 element rule. (would throw exception)

Set Array Size For All Variables Using Same Structure / Type

Oct 30, 2010

I found out that you cannot set the array size for a structure when you are making it, i.e

[Code]...

I have to fix this by making a variable with type made by Structure bullet and then redimming it, i.e

[Code]...

This means for every variable with the bullet type i create i have to redim. Is there a way i can set the size of .mesh with .capacity for every single variable created with the bullet type automatically?

VS 2005 Declare Size Of Array In Structure

Dec 11, 2009

I am upgrading a project from VB6 to VB.NET. Unfortunately, I cannot include the DLL or even the name of the DLL that I am using here, I am under a confidentiality agreement. However, I hope I can post enough info here to get this frustrating problem solved.

In VB.net: Code:

So, if I run it as such, it errors out while calling SetParameters saying
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

If I comment out the line m_Parameters.SProperties = New S_Properties(9) {...}, then it does not error out, however the function returns 0, which means it did not actually set the parameters to the device. Trying to ReDim SParameters(9) will also give the hresult error. Doing it with my example above, I put a watch on m_Parameters in both VB6 and VB.net and they look IDENTICAL. All data is the same. Why would I get this ArgumentException in VB.NET and not in VB6 when I am passing in the exact same arguments as in VB6?

VS 2008 Getting File Size From An Array Into ListView?

Mar 13, 2010

I'm attempting to get the size of a bunch of files located in a directory with an array. Using a single file, it works great. But as an array, I get an error. This is the code I was using:

VB .NET
Dim filepath() As String = Directory.GetFiles("C:Test", "*", SearchOption.AllDirectories)
Dim lvi As New ListViewItem
Dim fi As New FileInfo(filepath.ToString)

[code]....

It works... kind of. It adds each file to the ListView, when I just want the whole sum. I was hoping I could just use "DirectoryInfo" from the System.IO namespace, but everything I've been reading says I need to loop through the files.

.net - Check That Extension Methods On An Array Got A Specific Size?

I'm using extension methods based on an array and I would like to know if there is an easy way to check that array got a specify size instead of me doing a copy paste of

throw new exception "size of the array does not match"

this a small sample of extensions that I use, I got WAY more

<Extension()>
Public Function IsWhite(ByVal board() As bitPiece, ByVal pos As Integer) As Boolean
Return (board(pos) And bitPiece.White) = bitPiece.White

Create A Program That Accepts A Square Array Size 4 By 4

Nov 6, 2010

Trying to create a program that accepts a square array size 4 by 4. Then it should print the totals of the rows and columns. I started with a form and made text boxes and created a print button. I made it so that numbers can be input into the boxes. When hitting the print button, it should print the totals of what was input, however, it isn't doing that. Is there a different way to write the array code so that it will print it? Should i not have text boxes but rather have labels with fixed numbers set in them?

Create And Initialize An Array Of Structures Of A Fixed Size?

Mar 6, 2012

I am trying to create and initialize an array of structures of a fixed size. Each struct will be populated when a button is clicked. Here is an example of my struct:

public structure buttonStruct
dim x() as Boolean
dim y() as Boolean

[code]....

In my form_load function I am declaring the array of structs and:

Dim BtnStruct(15) As ButtonStruct
BtnStruct(0).Initialize()

[code]....

Whenever a specific button is clicked, I am trying to collect data and store it in the respective struct and so for example, if button 1 is clicked then I will store the data associated with button 1 into BtnStruct(0). The position of the button is stored in a public variable called BtnNum. If I attempt to store information in the struct inside another function as follows, I receive an error

BtnStruct(BtnNum).x(pos - 1) = temp "btnstruct is not declared. it may not be inaccessible due to its protection level"
